The story is simple, yet has a twist, and the ending non cliché.
I didn't know what to expect when first watching this, but it's definitely a beautiful piece of work.
Don't get why everyone is complaining about the accents and voice acting. Granted, there is room for improvement with the voice acting, but just because there is a foreign accent does not make the animation any less credible. I feel as if people want every animation to speak in perfect English or American accents. Even if there was no sound, but subtitles, the story would still be beautiful alone.
Just my feelings, really enjoyed this work of art.
